Screenshot of the error message.
Sorry for the late reply on this. I think I have this fixed for the next update. If you are still having problems, could you please try this?
Hold down Shift as Scrivener launches (this prevents any projects from being opened).
Does Scrivener start if you do this? Can you create new project? Is it only certain projects that see the crash? (Could you please send us one if so?)
Thanks and all the best,
